specification. A

This invention relates tomeans for combining ventilation with privacy, and is an improvement on the device invented by me and described in United States Letters-Patent No. 802,000 issued October 17, 1905.

In the accompanying drawings, forming a part of this speciiication, in which like numbers of reference denote like parts wherever they occur, house-shutter equipped with my device; Fig. 2 is a sectiona view, on the line 2-2, Fig. 1, loo to the right, the full lines showin the s ats in Ventilating position, while t e dotted lines show same closed by wind pressure from without Fig. 3 shows the construction of the hinged portion of the slats Figs. 4 and 5 illustrate modifications thereof; Fig. 6 is a perspective fragmentary detail of the facing of the side frames which directly receives the rod or pintle on which the slats are ivoted; and Fig. 7 is a detail ofthe sector lodli.

The shutter frame 1 may be of any desired construction. Within same is located a metal frame 2 ,having the flange 3, by which it is screwed or otherwise secured to the frame 1. Said metal frame 2 is formed with a ridge on the inside of its lower portion and with a groove 4 across the inside of its u per portion. Attached to each side of t e metal Jframe' 2 is a cleat 6 ,provided with recesses 7. A plurality of V-shaped slats 8, having independently-movable wings 9 are pivoted in said cleats 6 by rods or pintles 10, which pass through sleeves 11 and 12 on the wings 9 and enter the recesses 7. Controlling-rods 13 and 14 are attached by staples or other suitable means to the inner and outer wings 9, respectively, so that all the wings of either serieswill move together; and, by means vof devices yet to be described, both 'series may be caused to move in unison by the actuation of the controlling-rod 13. l

VThe sector 15, by means of its irregular radial arm 16, is attached to the outer wing 9 of one of the V-shaped slats 8, and, Aby reason of thc- L 17 of said arm 16, when the sector 15 Figure 1 is a front view of a.

V the movement iscaused to move, movement is imparted, also, to the wing 9 to which said L is attached, both traveling in the same arc of a circle. As the controlling-rod 14 is connected to the wing 9 thus actuated by said sector 15, motion is thus communicated through iti-rom the sector to the other win s 9 in the same outer series.

15 lpasses through the slot 18 in the frame 1, the flange 3 and plate 19 covering said slot and preventing vision therethrough and beingthemselves slotted so as neatly to iit said sector 15- and aiiording bearings therefor. The inner end of said sector 15 is elongated, and provided with a lurality of perforations or recesses 20, where y said sector and all the wings 9 of both series may be locked in any desired `position by means hereinafter described. Y

A bifurcated stud 21 fixed to one of the inner wings 9 and provided with a leaf spring -22 bearing pin v23 locks the inner series of wings 9 in any desired position by means of the protrusion oi said pin 23 through one of the openings 20. When thus locked (as in the position shown in Fig. 2, for instance) ofthe controlling-rod 13, or of the sector 15, or of one of the inner wings 9, or ofthe outer Wings 9 by wind-pressure (for instance), will cause all the V-shaped slats 8 and connected parts to move in unison.

In Fig. 3 I have shown my preferred means for pivoting the wings 9 so that each one may be movable either independently of, or in conjunction with, its partner. Each inner wing 9 is provided with a long sleeve 11 adjacent the middle of its length, and each outer wing 9 is provided with a pairof short sleeves 12 at a point not opposite said sleeve 1 1 on the companion wing. All these sleeves are arranged in alinement with each other, so that the rod or pintle 10 can pass through them all and Aenter the recesses 7. Said sleeves and rod formA the apex 4of the V- shaped The ridge 5 and the projection 24 above the apex of the highest V-shaped slat entering into the groove 4, prevent v1s1on above o r below the main device. The use\ of the notches 25 is for a similar purpose, and has been described in my former patent.

I yFigs` 4 and 5 illustrate modiiications of the means shown in Fig. 3 for pivoting the V-shaped slats. In Fig. 5, the only change slats when the rod is in position.

IOO

the present device each series of'wings 9: is

consists in having a single sleeve 26 on each wing, each of said sleeves occupying about one-half. of the lengthl thereof'. In Fig. 4, the rod 27 is shorter than the rod 10, and is inserted in tubular portions 28 of cylindrical enlargements 29 (solid or plugged at their ends) formed integral with the air of wings 9 shown in Fig. 4. The solid en 30 serve as pivots for the V-shaped slats in this construction.

It will be obvious that many minor` changes in the form and arrangement of the several. parts of my said invention may be made Without departing from the nature and spirit thereof. For instance, the terms inner and outer as hereinabove used are relative, andi the arrangement can easily bereversed if! desired.

With the device described in in former patent No. 802,000, it was impossib e, o to the integral construction ofthe V shape slats, for a person in the house who desired! to look out to seebetweenthe slats, but in independently actuatable, and eachseries can be raised' to the positionshown in the dotted lines in Fig. 2, orto any other desired angle, and both series of wings 9 thuspracp for detachably connecting said sector to the inner one lofsaid controlling means.
